Serial swept source optical coherence tomography of a cotton wool spot following SARS CoV2 infection
Indian Journal of Ophthalmology, 2021 A 33-year-old male presented with history of blurring of vision in the left eye for two months. He was seen by the local ophthalmologist and diagnosed as nongranulomatous anterior uveitis in the left eye with normal fundus.

Phase-stability optimization of swept-source optical coherence tomography [PDF]
Biomedical Optics Express, 2018 Phase-resolved imaging of swept-source optical coherence tomography (SS-OCT) is subject to phase measurement instabilities involved with the sweep variation of a frequency-swept source. In general, optically generated timing references are utilized to track the variations imposed on OCT signals.

Application and progress of swept source optical coherence tomography in choroid-related diseases
Yanke XuebaoCentral serous chorioretinopathy (CSC) is one of the choroidal spectrum diseases, characterized by choriod thickening and increased vascular permeability. Therefore it is very important to observe choroid, as this allows us to monitor it and formulate an

Real-Time Experimental Measurement of Swept Source VCSEL Properties Relevant to OCT Imaging
IEEE Photonics Journal, 2017 A real-time study of the dynamic properties of a frequency swept vertical cavity surface emitting laser (VCSEL) is presented. Such tunable laser sources have previously been shown to provide long coherence lengths and improved performance in metrology ...

Swept-source visible-light optical coherence tomography
Optics LettersWe demonstrate the feasibility of swept-source visible-light optical coherence tomography (SS-vis-OCT). We used a fanout periodically poled lithium niobate (PPLN) crystal for second harmonic generation (SHG) to convert a commercial near-infrared swept-source (NIR-SS) laser into a visible-light SS laser.
